Be it known that I, HUMPHREY FALYE'Y; a citizen of the United States, and-a resiborough of Brookl n, in the county of Kings and State 0 New York, have ins. vented anew and Improved Glass-Guttin Machine, of which'the following is a fulf clear, and exact description. Y

I This invention relates to improvenients in glass cutting devices, and particularly to a. device for quickly cuttin plate glass of an improved arrangement which wil adapt itselfto plate glass of different thicknesses,

and also glass which may not be perfectly 11 continually at right angles to the strai edge 5. Arm 15 extends downwardly an is formed into a pointer 23, which pointer "be shown as inches, meters, or any other de sired scale,

fiat.

Another object in view is. to provide a device with a supporting-platform for plate glass, and means-movable in two directions across the support so as to cut plate glass arranged thereon I in two directions and thereby'produce a perfectly square product. In the accompanying drawings- Figure 1' is e planviewof hn embodimentof the invention; Fig. '2 isa section through Fig. 1 approximately on line 22, the same beingon an enlarged scale; Fig, 3is a section through Fig. 2=on line3-3; Fig. 4 .1s a detailed fragmentary sectional view approxi- H'OfFig BQ by numerals, 1 indicates dation of any desired kind to which are se cured guiding strips 23 and flr, which guidof any desired mastrips are shifw'n' more in detailin '3' wherein it will jbe seenkthefle is provided a v overhanging members -6 are designed to on suitable pins .of the invention.
